Varieties of boilers Lemax
Most of the products are floor standing boilers. They are in great demand among consumers and are bought for private houses because of their high power and reliability.
It is more convenient to install wall devices in the apartment. Their principle of operation is based on the operation of the burner, which is built into the body. It heats up the heat exchanger. The circulation is natural or forced.
Gas floor heaters are produced with the following types of heat exchangers:
- Of steel. The thickness is 2 mm.
- Made of cast iron with a thickness of 4 mm. It is considered the best heat exchanger for a single-circuit heating boiler Lemax.
Devices differ in power, functionality and control method.
Boiler installation and adjustment
In order for the Lemax boiler to function without problems and breakdowns, it is important to install and connect it correctly. The installation should be trusted by professional workers, especially if the user does not have the skill to connect heating equipment.
The main requirement for installation is the provision of intensive removal of combustion products. The manufacturer recommends connecting a draft device made of sandwich pipes to the chimney.
Startup and connection is simple and fast.The factory settings are suitable for operation; they can be adjusted mechanically.
The gas valve plays an important role in the automation unit. This is a device that controls sensors or controllers that receive information from sensors. The product can consist of two valves - conventional and electromagnetic. When starting the second one is opened by pressing the button to ignite the wick. The user can then release the button. When the igniter is blown out, the thermocouple will cool down and the valve will close. The other spring valve will close after a signal from the draft and temperature sensor.
Common problems
Damage may occur when working with the equipment. The main types of malfunctions include:
- Problems with water heating. The device cannot dispense the required amount of liquid. To prevent this situation from happening, it is recommended to buy a single-circuit boiler and connect an indirect heating boiler to it separately.
- Spontaneous burner shutdown. Caused by problems with traction or breakdown of the temperature controller.
- Smell of gas. Leaks can be due to poor gaskets in the connections. Their replacement is required.
- Long red flame appears. Caused by insufficient draft or plugged burner.
- Cooling down of the battery when the boiler is hot. Little coolant or incorrect installation.
The main hardware problems are listed. You can fix them yourself. Complex breakdowns should be trusted only by specialists.
In case of problems with the draft sensor, you need to replace it with a new one. The part can be purchased at any specialty store. If the problem is with the igniter, it must be reconfigured. You can read the adjustment information in the instructions.

The Wester Clever line is represented by four atmospheric convection boilers with different power ratings. For example, the Wester Clever 30 has an efficiency of up to 90% and a heating power of 34 kW. The Wester Clever 40 model has a large capacity and a heating capacity of 45 kW.
The premium line is installed in rooms equipped with a chimney. Power range from 8 to 100 kW. There are modifications with one and two circuits. Both connection methods are available - left and right. There is an automatic regulation of the intensity of the flame. The heat exchanger is treated with anti-corrosion impregnation. An example is a single-circuit atmospheric boiler Premium 16 with an efficiency of 90%. The gas boiler Lemax Premium 16 has a power of 16 kW and is capable of heating an area up to 160 sq.m. The line includes an upgraded version of the Premium Nova with automatic controls that support the set parameters. There is an adjustment of the coolant pressure.
Patriot is suitable for installation with any kind of ventilation (natural or forced). There are parapet and wall versions for installation in the apartment. Combustion products are discharged through a coaxial chimney. The average power is 6-20 kW.
Wise products are made of 4mm Czech cast iron. They have an optimal ratio of water volume to the mass of the heat exchanger. The devices are stable against fluctuations in temperature and pressure. There is a possibility of transferring to liquefied fuel, connecting additional indirect heating tanks, thermostats, control systems. The average heating capacity is 16-60 kW.
The leader is also equipped with a cast iron heat exchanger. The surface is silver plated. An injection burner is located in the lower part of the furnace. They have only one circuit and are capable of heating an area of 150 sq.m. up to 500 sq.m. The power is 19-55 kW. They are among the most expensive items. The service life is 25 years.
Safety and operating rules
Each model is equipped with a security system that includes the following elements:
- overheat protection;
- thrust sensor;
- fire extinguishing protection;
- protection against the appearance of soot and precipitation.
